Quark-Quark and Quark-nucleon Potential model Extended-soft-core meson-exchange Interactions
Th. A. Rijken, Y. Yamamoto
The Quark-quark (QQ) and Quark-nucleon (QN) interactions in this paper are derived from the Extended-soft-core (ESC) interactions. The meson-quark-quark (MQQ) vertices are determin…

Nucleon-quark mixed matter and neutron star EOS
Y. Yamamoto, N. Yasutake, Th. A. Rijken
The nucleon-quark mixed matter is defined in the Brueckner-Hartree-Fock framework, in which quark densities are determined by equilibrium conditions between nucleon and quark chemi…

Quark phases in neutron stars consistent with implications of NICER
Y. Yamamoto, N. Yasutake, Th. A. Rijken
The analyses for the NICER data imply km and km, indicating the lack of significant variation of the r…
